import View360 from "@site/src/components/View360";
import OptionDescriptor from "@site/src/components/OptionDescriptor";

<OptionDescriptor type="Record<string, string>" defaultVal="{}" added="4.0.0" />

Override default class names.
You can use it to set a different class name for the control bar element.


## Example
Below is an example of changing the class of the container element (`.view360-spinner`).

```js
import { LoadingSpinner } from "@egjs/view360";

new LoadingSpinner({
  className: {
    CONTAINER: "new-container-classname"
  }
})
```
